4 Claims.

This invention relates to lamp shade construction, and particularly to a novel construction and arrangement of the covering material, and to novel means for securing the covering material of the shade to the frame thereof.

One object of the present invention is to provide novel means for securing the covering material to a lamp shade frame without the extensive use of stitching or the like.

Another object of the invention is to provide a novel construction and arrangement in a lamp shade cover to facilitate the fitting of the covering material of the shade structure to the frame thereof.

Another object of the invention is to provide a'novel construction and arrangement of a lamp shade and supporting means therefor.

A further object of the invention is to provide a simple, inexpensive, and emcient arrangement to facilitate the securing of the covering material to a lamp shade frame in a minimum amount of time.

A still further object of the invention is to improve devices of the character described in sundry details hereinafter referred to and particularly pointed out in the appended claims.

One embodiment of the present invention is shown for illustrative purposes in the drawing, in which:

Fig. 1 is an elevational view of a lamp shade structure embodying features of the present invention, a portion of the shade structure being broken away to better illustrate the construction thereof;

Fig. 2 is an enlarged sectional elevational view of the structure illustrated in Fig. 1, and taken substantially as indicated'by the line 22 thereof;

Fig. 3 is an enlarged fragmentary side elevational View of a portion of the structure illustrated in Figs. 1 and 2;

Fig. 4 is a fragmentary plan view on an intermediate scale of a portion of the structure shown in Figs. 1 to 3, inclusive, and illustrating the manner of securing a supporting bracket thereto;

Fig. 5 is an enlarged fragmentary sectional elevational view of the structure illustrated in Fig. 4, and taken substantially as indicated by the line 55 thereof; and

Fig. 6 is a fragmentary elevational view of a portion of the frame cover or covering material, and illustrating the arrangement of the elements employed in the construction thereof.

In the drawing, the present invention is illustrated as applied to a lamp shade construction shown, in the present instance, as comprising a frame having an upper frame member indicated by the numeral II and a lower frame member I 2 connected together and laterally spaced apart by means shown, in the present instance, as a plurality of rods I 3 positioned at intervals around the shade structure, the shade when finished including a covering material indicated, as a whole, by the numeral l,-and adapted to surround and cover the frame members and 2 and the rods l3, the upper portion of the shade member being finished off with a strip of braid l5, or other suitable trim, as illustrated in Fig. 1.

It will be noted by reference to Figs. 1 and 2 that the lower frame member l2 isof substantially greater diameter than the upper frame member H and, as clearly illustrated in Figs. 2 and 6, the covering material or member Id comprises a pleated outer ply l8 formed, preferably, of an elongated strip of fabric or the like, having a strip I! of ordinary tape secured adjacent a longitudinal edge portion l8 thereof by'stitching l9, and provided adjacent its opposite longitudinal edge portion 2| with a strip 22 of bias tape secured thereto, preferably, by means of adhesive on one side of the tape 22, thereby providing a structure whereby a degree of elasticity is obtained along the last-mentioned edge portion 2| of the ply It to permit of elongating the edge portion 2| to surround the frame member 2 and provide a uniform distribution and taper of the pleats on the outer ply surrounding the frame, as illustrated in Fig. 1.

After the length of the edge portion 2| has been determined according to the circumferential dimension of the frame member l2, one edge portion of a preferably plain inner ply or lining 23 is secured to the edge portion 2| and the bias tape 22, preferably, by means'of'stitching 24, and the opposite edge portion of the plain ply or lining 23 is folded back upon itself and stitched,

as indicated at 25, to provide a loop adapted to,

receive an annular, resilient, hoop-like retaining ring or member 26 shown, in the present instance, as having an inner diametrical dimension somewhat less than the outside dimension of the upper frame member H.

For readily securing the covering member M to the lamp shade frame in a minimum of time, the ring or retaining member 26, with the edge portion of the inner ply or lining 23 secured thereto, is slipped over the upper frame member in a manner to position the ring 26 outside the frame and between the upper and lower frame members II and I2, respectively, as clearly illustrated in Fig. 2, it being understood, that to accomplish this, one side of the ring 26 may be positioned well under one side of the upper frame member due to the wide spacing of the bars I 3, and the ring 26 sprung outwardly over 2 the upper frame member H and down along the inner side of the frame and around the lower frame member l2, adjacent which the bias taped edge portion 2| of the pleated outer ply I6 is positioned, the outer ply l6 being adapted to extend upwardly on the outer side of the lamp shade frame in a manner to position the opposite edge portion l8 of the pleated ply l6 adjacent the looped edge portion of the inner ply 23 and the upper frame member H where it is secured in such position by means of long stitches 21 passing through the tape l1, pleated ply l6, looped edge portion of the inner ply or lining 23, and a winding 28 of tape or other suitable material surrounding the upper frame member II.

It will be observed that by such an arrangement, the covering material may be readily and quickly applied to the frame of the lamp shade merely by slipping the hoop-like retaining ring or member 26 over and around the upper edge portion of the shade frame and passing the covering material downwardly inside the frame and around the lower frame member [2, thence upwardly on the outer side of the frame and secured to the frame member H by the long stitches 21, it being understood that by reason of the elasticity of the bias tape 22, the lower edge portion 2| of the pleated ply l6 may be stretched or extended to completely surround the larger frame member I2 to position the pleats uniformly around the frame member at both top and bottom and provide a uniform taper of the pleats toward the upper portion of the shade.

For suitably supporting the lamp shade struc ture on a light fixture or the like (not shown),

a bracket having arms, one of which is shown in Figs. 4 and 5 and indicated at 29, provided with a hook portion 3| adapted to overlie and partially surround the upper frame member ll outside the adjacent folded portion of the inner ply or lining 23 and, preferably, inside the edge portion I8 of the pleated ply It, as clearly illustrated in Figs. 4 and 5. 1

It will be observed from the foregoing description that the present invention provides a-novel construction and arrangement whereby the covering material may be readily and quickly secured to a lamp shade frame with a minimum of stitching, and wherein the covering material is so constructed as to facilitate the fitting of the covering material of a shade structure to the frame.

Also, that the present invention provides a novel construction and arrangement whereby a 1 supporting means may be applied to the shade structure after the covering material has been positioned thereon.

Obviously, the present invention is not limited to the precise construction and arrangement shown and described as the same may be variously modified. Moreover, all the featuresof the invention need not be used conjointly as the same may be used to advantage in variously different combinations and sub-combinations.

What I claim as new and desire to secure by Letters Patent is: I j

1. In a lamp shade and in combination, a frame comprising upper and lower-frame members relatively fixed in spaced relation with respect to each other, an endless substantially rigid hoop-like member surrounding said frame adjacent one of said frame members, a covering material having one of its edge portions secured to said hoop-like member and extending around said frame members, and means for securing the opposite edge portion of said covering material to the frame member adjacent said hoop-like member.
